9 Claims.

My invention relates to thread guides for winding machines and. moreparticularly tomeans for mounting and attaching a guide eye to itssupport.

i In application, Serial No. 708,480, filed January 26, 1934;now Patent1,965,044, issued July 3, 1934,

I have disclosed athread guide fastening means in combination with afaller arm structure, wherein the guide may be easily and quicklyreplaced without the use of any special tool. The present invention isan improvement over the arrangement disclosed in the above referred toapplication and relates to a thread guide fastening device of generalapplication with winding machines and various attachments usedtherewith.

An object of my invention is to provide a fastening means for threadguides whereby the guide. eye may be readily attached or detached fromits support arm or bracket.

Another object of my. invention is to provide an improved locking-meansfor the guide fastening device whereby the guide is held in tightengagement with its support. I I

Still another object of my invention is to provide an improved threadguide eye adapted to be used in combination with-various types ofwinding machine structures and attachments used therewith. I

With these and other objects in view, which may be incident to myimprovements, the inven- 7 tion consists in the parts and combinationsto be hereinafter set forth and claimed, with the understanding that theseveral necessary elements, comprising my invention, may be varied inconstruction, proportions and arrangement, without departing from thespirit and scope of the appended claims.

In order to make my invention -more clearly understood, I have showninthe accompanying drawing means for carrying the same into practicaleiiect, without limiting the improvements in their useful applicationsto the particular constructions; which for the purpose of explanation,have been made the subject of illustration.

Referring to the drawing and more particularmodithread cleanercomprising a body portion I having arms 2, 2' extending outwardlytherefrom and r a conventional blade support member, through which thethread 3' passes. Each arm is provided with a thread guide supportmember 4 adapted to'thread into the arm and heldin position on the armby means of suitable lock nuts 5. The support member is threaded as at 6and is further providedwith a head I having an opening 8 formed therein.Attached to the end 9 of the support member is a thread guide designatedgenerally by numeral Ill, formed with a longitudinal recess II, a recessl'zextending perpendicular to the longitudinal recess and a groove I3 atthe rear thereof, parallel to opening I2. 7

In order to maintain the thread guide II! in fixed position on thesupport member 4, there is provided a looped member I4 having one end I5threaded through the opening 8 formed in the head I of the supportmember, the other end I6 of said looped member seating in recess I2formed in the body of the guide. The loop member may be in the form ofwire and it is bent as at I! to provide a spring action when the endsofthe wire are inserted in the respective openings. v It will be notedthat portion I8 of the wire seats in the groove I3 formed at the rearofthe thread guide, the purpose of this arrangement being to preventlateral movement of the guide withrespect to its support. e V v Inmounting the-guide, loop member I4 'is-rotated away from the end of thesupport member so that the thread guide will clear the end of ly toFigures 1 and 2 thereof, there is shown a the wire when the recessportion II receives the end 9 of the support. After the guide'is placedin position on the end of the support, end'IB of the wire is insertedinto recess I2 formed in the body of the guide, portion I8 of the wireseating in the groove I3 formed at the end of the guide. Referring toFigures 3 and 4, there is shown a modification of the invention adaptedto be used for mounting and supporting a thread guide on the frame orother parts of a winding machine.

In this arrangement, the support comprises a threaded member which maybe in the form of a wood screw l9 having a flat substantiallyrectangular shaped head 20 having an opening 20' formed therein. Threadguide I0 is provided with an opening 2| adapted to receive one end 22 ofthe loop member used in fastening the guide to the support. The guide isalso provided with a longitudinal recess 23 in which the head 20 of thesupport I 9 seats, and a groove 24 which forms a seat for the straightportion 25 of the loop member when the guide is attached to the support.

Referring to Figures 5 and 6, there is shown a further modification ofthe arran ement disclosed in Figure 3, wherein the support member isv inthe form of a machined screw. The purpose of this arrangement is toenable the support to be readily attached to metallicportions of awinding machine, the support being held in po- Sition .on the machine:by means of suitable lock nuts. The thread guide and locking means forthe guide together with the head portion of the support member aresimilar to the structure disclosed in Figure 3.

Referring to Figure 7, I have shown another modified form of theimproved thread guide support and locking means therefor, comprising abolt 26 having a head 2! formed with a slot .28. The bolt is providedwith .a longitudinal recess .29 adapted to receive the end 30 of thelooped member 3|. In .this arrangement, the thread guide In is held inposition on the end .of the bolt by means of looped member 3.], one end32 .of which passes through opening- 33 formed in the body of the guide,the other end of the looped member being bent around so that a portion34 seats in the slot 28, the end 30 resting in the recess 29 formed inthe .body of the bolt.

Referring to Figures 8 and 9, there :is shown a .further modification ofthe thread guide mounting comprising a .bolt .35 formed with ashouldered portion 36 and a flat projection 31. The thread guide is heldin position on the bolt by means of a spring clip member provided witharms 38, .38. ,As more clearly shown in Figure 8, the clip member isprovided with an intermediate portion .38 having an opening 40 adaptedto receive the end of the bolt. In the arrangement shown in Fig. .9, theguide is formed with a longitudinal recess to accommodate projection 31,and is held in the operative position on the bolt by means .of the clip,arms 38, 38' .of which engage with the body of the guide.

Referring to Figure 1.0, I have shown a modification oi the arrangementshown in Figure .8, wherein the clip. is held in position .on the boltby means .of ajam-nut M. In this form of the .device the thread guideseatson the head portion 42 .of the bolt, the body of the guide beingsesurely clamped between the arms of the clip.

While I have shown and described the preferred embodiment of myinvention, I wish it to be understood that I do not confine myself tothe precise details of construction herein set forth, by way .ofillustrations, as it is apparent that many changes and variations may bemade therein, by those skilled in the art, without departing from thespirit of the invention, or exceeding thescope of the appended claims.
